This is a followup from an earlier blog. The Somali pirates I mentioned a few days ago were chased off using a frightening new sonic weapon...

"The sonic device, known as a Long Range Acoustic Device, or LRAD, is a so-called "non-lethal weapon" developed for the military after the 2000 attack on the USS Cole in Yemen as a way to keep operators of small boats from approaching U.S. warships.

Makers of the device compare its shrill tone to that of smoke detectors, only much louder.
